Image A. The CT scan of her abdomen had the appearances shown here. She also has small pulmonary nodules. Bioposy of the liver revealed hyphae consistent with Aspergillus.
Image B. She responded well to oral itraconazole therapy.

This image shows the pelvis of the left kidney filled with fungal balls. Eventually, after failing amphotericin B therapy, she required a nephrectomy. Her case is reported in Davies SP, Webb WJS, Patou G, Murray WK, Denning DW. Renal aspergilloma – a case illustrating the problems of medical therapy. Nephrol Dial Transplant 1987; 2: 568-572.

Aspergillus keratitis. Good example of Aspergillus keratitis caused by A.glaucus. Usually A.fumitagus and A.flavus are the causes.
